Nivio Ziviani (Belo Horizonte - Brazil, August 27, 1946) is a Professor Emeritus[1] at the Department of Computer Science of the Federal University of Minas Gerais (UFMG). He has a Ph.D. in Computer Science from the University of Waterloo, Canada, 1982.[2] Nivio Ziviani is well known for his research in computer science,[3] mainly focused on Information Retrieval, Algorithms and Web Recommender Systems,[4] as can be seen in his DBLP[5] and Google Scholar.[6] He is member of the Brazilian Academy of Sciences[7] and the National Order of the Scientific Merit in the class Comendador .[8] In 2011 he received the Prize of Scientific Merit of the Brazilian Computer Science Society.[1] He has Erdős number 2.[9][10]

Nivio Ziviani is author of the following books about algorithms:

  • Projeto de Algoritmos Com implementações em Pascal e em C[11] (Cengage Learning, ISBN 9788522110506, Third Edition, 2010) (in Portuguese).
  • Diseño de Algoritmos com implementaciones en Pascal y C[12](Thomson Learning, ISBN 978-84-9732-538-7, 2007) (in Spanish, translated from the Portuguese version).
  • Projeto de Algoritmos Com implementações em Java e C++[13] (Thomson Learning, ISBN 85-221-0525-1, Second Edition, 2007) (in Portuguese).

He was the creator of one of the first search engines.[1] He co-founded the Miner Technology Group in 1998, which was acquired by Group Folha de São Paulo / UOL in 1999, and a search engine company called Akwan Information Technologies in 2000, which was acquired by Google Inc. in 2005[1] - an acquisition that became worldwide news. With Akwan, Google bootstrapped its R&D Center for Latin America,[14][15] which is located in Belo Horizonte. Nowadays he is also co-founder and the Chairman of the Board of Zunnit Technologies,[16] a start-up company focused on software for recommending items of interest to Web users, and co-founder of Neemu.

At UFMG he coordinates the Laboratory for Treating Information (LATIN), [16] and is co-founder of the Information Retrieval Group at UFMG. He has co-authored over 100 refereed papers and 2 books in algorithm design and information retrieval, the latter his primary area of research. Nivio Ziviani was the General Co-Chair of the 28th ACM SIGIR Conference on Research and Development in Information Retrieval[17] and co-founder and member of the Steering Committee of the International Conference on String Processing and Information Retrieval (SPIRE).[17][18]

Research Impact[edit]

As a result of more than 30 years teaching and researching[19] he has a great list of graduate students and research projects. One example of his research projects with great impact is the C Minimal Perfect Hashing Library (CMPH),[20] which is an open source library with more than 10,500 downloads.[21]
